Title: Rhodium on carbon catalyst
Inventor: SCHROEDER HOBE
IPC: C07B61/00
Filed: 1986-10-07
Granted: 1993-06-17
Abstract: A particulate catalyst composition suitable for purification of terephthalic acid under reducing condi­tions and a method of preparation of such catalyst are disclosed. The catalyst composition includes catalyti­cally active rhodium on a porous, granular, carbonaceous support material having a surface area of at least about 600 cm²/gram. Rhodium is present in an amount of about 0.01 to about 2 weight percent, based on the total weight of dry catalyst composition and calculated as elemental metal. In the presence of hydrogen, this catalyst exhi­bits a reduced terephthalic acid decomposition rate that is comparable to that for a palladium-on-carbon catalyst having the same catalyst metal loading. The catalyst is prepared by contacting a carbonaceous support material having a surface area of at least 600m²/gm and a pH value in its aqueous suspension of 9-11 with an aqueous rhodium salt solution having a pH of 1-4.

Abstract: The scheme starts up and restarts the full electronics exchanger so that the efficient broadcasting loading is initialized according to the system characteristics. The method comprises: the first step(200,204) of converting the point to point loading into the broadcasting scheme; the second step (300,301,311) of performing the broadcasting load; the third step of converting the broadcasting scheme into the point to pint scheme.

Abstract: 본 발명은 액체투과성 상부시트와 솜털펄프 및 액체불투과성 배면시트를 기본구성요소로서 포함하며 하나이상의 구성요소에 고흡수성 수지와 원적외선 방사 세라믹이 함유되어 있고 브래지어컵 안쪽에 부착하여 사용할 수 있는 일회용 모유 흡수제품을 제공하는 것으로서, 이러한 일회용 모유 흡수제품을 브래지어컵 안쪽에 부착하여 사용하면 수유부와 같이 모유분비가 많은 경우 모유를 흡수처리하여 브래지어가 젖거나 브래지어 밖으로 새는 것을 방지할 수 있고 또한 분비된 모유로 인한 비린 냄새를 소취하여 매우 위생적인 잇점이 있다.
